Filimka Polyethylene Miisaanka Sare ee Molecular

Filimka Polyethylene ee Miisaanka Sare ee Aad u Sareeya Sawirka La Soo Bandhigay

sharraxaad gaaban:

Filimka polyethylene-ka miisaanka molecular-ka aadka u sarreeya (UPE) ayaa noqday walax ceeriin ah oo warshadeed oo si weyn loo isticmaalo sababtoo ah iska caabinta xirashada oo sareysa, iska caabinta saameynta iyo is-milmaynta. Waxaa si ballaaran loogu isticmaalaa suufka cagta, istiikarrada cagta, agabka dahaarka leh, gaskets-ka u adkaysta xirashada, suufka cagaha ee alaabta guriga, siligyada, looxyada u adkaysta xirashada, agabka baakadaha iyo munaasabadaha iyo alaabada kale.

Tusaale ahaan, u qaado jiirka:

Marka la barbardhigo Teflon (polytetrafluoroethylene PTFE), oo ah walaxda loo isticmaalo suufka jiirka ee dhaqameed, filimka UPE ee polyethylene ee miisaanka molecular-ka aadka u sarreeya ayaa aad u adkaysta xirashada. Sifada is-saliidda ee UPE waxay u dhowdahay tan walaxda Teflon. Isla mar ahaantaana, marka laga eego qiimaha, cufnaanta filimka polyethylene ee miisaanka molecular-ka aadka u sarreeya ee UPE waa mid yar, polyethylene-ka miisaanka molecular-ka aadka u sarreeya ee UPE-na waa 50% ka hooseeya Teflon marka loo eego beddelka labajibbaaran. Sidaa darteed, filimka polyethylene ee miisaanka molecular-ka aadka u sarreeya (UPE) ayaa si tartiib tartiib ah u beddelay ferroazol oo ah doorashada koowaad ee alaabta ceeriin ee cagaha loogu talagalay warshadaha.

Adeegsiga goobta cajaladda:

Cajalad dhejis ah oo cadaadis-saamaynaysa oo ku salaysan filimka UHMWPE iyo lakabka sii deynta. Marka la barbar dhigo cajaladaha kale ee dhejiska ah ee isticmaala filimka resin, iska caabbinta saamaynta ayaa ka sarreysa, iska caabbinta xoqidda iyo is-saliidda ayaa ka wanaagsan.

Hordhac UHMWPE:

Polyethylene-ka miisaanka molecular-ka aadka u sarreeya (UHMW-PE) waxaa loola jeedaa polyethylene-ka toosan oo leh celcelis ahaan miisaan molecular ah oo ka badan 1.5 milyan. Sababtoo ah miisaankiisa molecular-ka ee aadka u sarreeya (polyethylene-ka caadiga ah waa 20,000 ilaa 300,000, UHMW-PE wuxuu leeyahay waxqabad dhammaystiran oo aan la barbar dhigi karin marka loo eego polyethylene-ka caadiga ah iyo balaastikada kale ee injineernimada:

1) Iska caabin aad u sarreysa oo xirasho ah, 4 jeer ka sarreeya nayloon 66 iyo PTFE, 6 jeer ka sarreeya birta kaarboonka, waana kan ugu fiican dhammaan resins-ka synthetic-ga ah ee hadda jira.

2) Xoogga saamaynta aad ayuu u sarreeyaa, kaas oo ah 2 jeer ka badan polycarbonate iyo 5 jeer ka badan ABS, wuxuuna ilaalin karaa adkeysi sare heerkulka nitrogen-ka dareeraha ah (-196 ℃).

3) Hanti wanaagsan oo is-saliidaynaysa, hantideeda is-saliidaynaysa waxay la mid tahay tan PTFE, isku-darka is-saliidaysankuna waa 0.07-0.11 oo keliya; waa 1/4-1/3 oo keliya isku-darka is-saliidaynta birta.

4) Qiimaha nuugista tamarta shoogga ayaa ah kan ugu sarreeya dhammaan balaastigga, saameynta yaraynta buuqana aad bay u wanaagsan tahay.

5) Waxay leedahay xasillooni kiimiko oo sareysa waxayna iska caabin kartaa warbaahinta kala duwan ee wax burburiya iyo warbaahinta dabiiciga ah heerkulka iyo xoogga la saarayo.

6) Awood xooggan oo ka hortagga dhegdheg, oo ka dambeysa "Plastic King" PTFE.

7) Waa nadiif gebi ahaanba ah oo aan sun ahayn, waxaa loo isticmaali karaa taabashada cuntada iyo daawada.

8) Cufnaanta ayaa ah tan ugu yar dhammaan balaastikada injineernimada, 56% way ka fudud tahay PTFE iyo 22% way ka fudud tahay polycarbonate; cufnaanta waa 1/8 birta, iwm.

Iyada oo ay ugu wacan tahay waxqabadka dhammaystiran ee kor ku xusan, UHMW-PE waxaa loogu yeeraa "balaastig cajiib ah" wadamada Yurub iyo Ameerika waxaana lagu qiimeeyay oo si weyn loogu isticmaalay warshado badan.
